A three-layered topper for a bedding or seating product has a first piece of foam, a second piece of foam and a pocketed spring comfort layer therebetween. The pocketed spring comfort layer has individually pocketed mini coil springs. At least one of the foam pieces may be infused with metallic particles to improve thermal conductivity. Alternatively, at least one of the foam pieces may be infused with microencapsulated phase change materials to improve heat absorption. At least one of the foam pieces may have a coating to further improve thermal conductivity or heat absorption.

A mattress assembly includes a first layer of viscoelastic foam defining an upper surface, and a second layer of non-viscoelasiic foam supporting the first layer. The mattress assembly also includes a plurality of static spring elements positioned beneath the upper surface for enhancing a firmness of the combined first and second layers.

A flippable mattress includes a first memory foam layer, a second memory foam layer, a core layer disposed therebetween and a transition layer between each foam layer and the core. The first memory foam layer has a thickness, and the second memory foam layer has a thickness that is greater than the thickness of the first memory foam layer. The first transition layer has an IFD less than that of the second transition layer. The mattress is flippable between a first orientation in which the first memory foam layer is above the core layer and the second memory foam layer, and a second orientation in which the second memory foam layer is above the core layer and the first memory foam layer.

Vertically lapped nonwoven material is used to provide enhanced breathability and comfort in mattresses by replacing foam material in one or more of, including all of top panel quilts, layers underneath the top panel quilts, and in side blocks which surround spring supports. The vertically lapped nonwoven may provide advantages in terms of cost, manufacturing ease, robustness in mattress design, while at the same time providing the user with a much more comfortable sleeping experience.

Hybrid coil and air chamber assemblies for cushioning supports generally include pressurized air chambers that are positioned intermediate strings of pocketed coils. In this manner, the coils and air chambers can move independently but can be made to cooperate to provide firmness control, contouring and/or support of a user thereof. Air pressure within the air chambers can be independently adjusted to manipulate firmness and/or contour properties in specific zones defined by the presence and location of the air chambers, e.g., pressure of the air chambers corresponding to the lumbar region can be adjusted to eliminate high pressure points. Still further, the pressure within the air chambers can be automatically adjusted to different applied loads as a function of movement. Also disclose are processes for adjusting a mattress including the hybrid coil and air assemblies.

The present invention is a spring unit for a mattress comprising first and second pocket springs. Each of the first and second pocket springs comprise a coil pocket comprising a pocket and a coil spring disposed in the pocket and a cushion pocket comprising a pocket and a first resilient member disposed in the pocket of the cushion pocket. Each cushion pocket is engaged with and acting only upon the corresponding coil pocket. Substantially the entire side of the pocket of the coil pocket of the first pocket spring is engaged with substantially the entire side of the pocket of the coil pocket of the second pocket spring. Each cushion pocket is free standing and not connected with each other thereby creating a pumping action upon depression of the first pocket spring and/or the second pocket spring that produces circulation of air within the mattress.

A mattress wherein a plurality of independent yarn based fire barrier fabrics encases a plurality of distinct and unattached interior core structures. The plurality of interior core structures include at least a detached and internally flippable upper comfort layer assembly with a plurality of non-homogeneous foams or filling materials encased in a yarn-based fire barrier fabric and a lower, interiorly disposed support core structure with resilient filling materials encased in a yarn-based fire barrier fabric and a fabric cover. The detachable and internally flippable upper comfort layer assembly may be contained in a user accessible compartment that is fashioned into an outer cover assembly.

A mattress including: a support surface to support a user; a mattress main body that constitutes the support surface; at least one pressure sensor having a flexible sheet shape to detect a pressure acting on the support surface; a support surface cover positioned with respect to the mattress main body and arranged so as to cover the support surface; and at least one positioning member provided to the support surface cover to permit a movement of the pressure sensor with respect to the support surface cover in a planar direction while limiting an amount of the movement of the pressure sensor with respect to the support surface cover in the planar direction such that the pressure sensor is positioned on the support surface by the positioning member.

Provided is a conveyance seat in which an increase in size is suppressed while an impact to be applied to a seated occupant when an impact such as a collision is generated is properly absorbed. A vehicle seat includes a seat cushion. The seat cushion includes a seat cushion frame including a pair of side frames provided to be separated from each other in a width direction of the vehicle seat, a seat cushion pad placed on the seat cushion frame, and an impact absorbing member provided below the seat cushion pad. The impact absorbing member is disposed between the pair of side frames in the width direction of the vehicle seat. The impact absorbing member is provided with a cavity portion. The impact absorbing member is supported from below by a plate-shaped member.
